DC20 maintains SET1 and/or SET2 subject temperature with accuracy(hysteresis), which can be
set in F12 and F22 parameter.
Depending on an application 1 and 2 Controller can work in HEATING or COOLING mode.
After choosing measurement form (F10 and F20 parameters) the controller is able
to operate in many variants, for example as a single heating controller with two settings
or as two separate heating controller or as a differential controller with an additional
alarm threshold at the same time.

6.2. DIGITAL INPUT.
Controller has D1 digital input, which can be used as an alarm input. Then it can signal
emergency states sound signalling, such as system failure, pressure control, safety t h e r m o s t a t
STB or safety button activation. Connect additional security system contacts to D1 contacts (4-5
terminals). Contacts type: NO (normally opened) or NC (normally closed) is set in F50 parameter.
